Answer:
686 crystals.
Step-by-step explanation:
You can set up an algebraic equation to find the answer.
Let x represent the number of crystals Lily uses.
The question is asking how many crystals it will take to raise 6,174 zombies, when each crystal raises 9.
9x = 6174
x = 6174 / 9
x = 686
That means it will take Lily 686 dark power crystals to raise 6,174. That's a lot of dark power!
Hope this helps!
Answer:
2/3
Step-by-step explanation:
1 - (1/12 + 2·1/8)
= 12/12 - (1/12 + 1/4)
= 12/12 - (1/12 + 3/12)
= 12/12 - 4/12
= 8/12 which reduces to 2/3
Answer:
0
Step-by-step explanation:
j(x) = -2 (3/2)^x
j(0) = -2(3/2)^0
-2(0)
=0
Answer:
Step-by-step explanation:
The midpoint is essentially a point with the average of the 2 x-coordinates and the 2 y-coordinates.
The formula is:
We are given two points: A (7,0) and B (0, 3). Remember points are written as (x, y).
Therefore,
Substitute the values into the formula.
Solve the numerators first.
The midpoint can be left like this because the fractions are reduced, but it can be written as decimals too.
Answer:
DE = 21
Step-by-step explanation:
Recall: the ratio of the corresponding side lengths of similar triangles are equal
Given that ∆ABC ~ ∆DEF, therefore,
AB/DE = BC/EF = AC/DF
AB = 8.4
DE = x
BC = 10
EF = 25
AC = 16.5
DF = 41.25
Let's find DE using AB/DE = BC/EF. Thus:
8.4/x = 10/25
Cross multiply
x*10 = 25*8.4
10x = 210
Divide both sides by 10
x = 210/10
x = 21
DE = x = 21
